v To mil whom it may concern:

r a. full,'cleor, and exact description, reference being bad to the accompanying drawings.

The object of my invention is to automatically make con-bodies, and particularly can-bodies which are flanged and bonded and have fist sides and rounded corners and have the seem in one of the corners.

- The invention includes the mechanism for feeding the metal-stock sheets into the machine the mechanism for cutting and form ing the blanks, the mechanism for bending the blanks into she e and interlocking their ends and ressing the interlockin edges to gether to orm the seem, the mec anism for automatically discharging the finished bodies, and to various other subordinate mechanisms which cooperate with the mechanisms above referred to to render the machine automatic and efficient, whereb Y said can-bodies may be produced rapidly on cheaply.

Although one of the main objects aimed at in designing the machine has been to produce substantially square can-bodies with rounded corners, the machine is adapted for making can-bodies of othershepes, depending rimarily, upon the shape of the form the machine contains and over which, the blanks are bent to form the bodies.

= In the bed-plate A of the machine is an enin large enough for the passage of the o bl en'k from which the can-body is to be made. Secured upon the bed plnte slightly overhanging this opening is a lowerfixed die 3, by which the blank is out from the stocksheet. :flhis die is a substantially rectanguler open frame, having a. frontinembor h and sides 2:, but no rear member. The stockfleet is drawn into the Front of the machine over this die B, by means which will be presently ex leined, until the advancing edge of said slice :s'heet cop es against the stop-lugs 5 blank is out from the stock-sheet betiwenthe fixed die B and the movable die.C,

which is on the lower end of a slide D. This slide is verticolly movable in guideways in the upright frame members a. The die 0 is rectangular and fits into the die 13 andis like it in tbet'it has a front members and two sides 0 c, but no rear member. There is another vertically-movable slide 13, 09 1 1 posed of a. member a, a member 2, and e er a, Whiiil'i, connects the rest ports of the members a and s so that all parts must move to other. The slide member a is movable in *"idesn'n the slide D, which are of course ebove'the level of the bed-plate A, while the slide member e is movable 1n guides a on the vertical position.

inner faces of the two side frame members (1 below said bed-plate. Said slide E is moved up and down by means of a connecting-rod a, mounted upon a crank carried by the main driving-s iaf t F.

Upon the upper edges of the lower slide ,member 6 the lower bending-dies G are secured. These dies are bars which are located directly beneath the side members 0 of the blank after it has been cut from the stocksheet. The object of the cooperative action of the bending-dies is to bend one edge of the blank upward at an inclination, as at n, and to bend downward into vertical )osition the extreme ed e n of this upwardfy-bent portion and to end the other edge of the blank correspondingly, but in the reverse directi0nthat is to say; to bend the blank down Ward at an inclination near its edge, as at 11 and to bend the extreme edge a upward into It is evident that when the bends at n and n are strai htened out the two edges a and n will not e at right angles to the body of the blank, but will make acute angles thereto, wherefore they may be easily interlocked when brought together. In the lower ed e of one of the side members 0 of the cutting-die C is a shallow ratchet-shaped groove 0 U on the top face of the corre sponding ben ing-die G is an upwardly-extended com lementarilyshaped rib At the other Sh e of the opening of the bed-plate a similar groove and rib are formed; but in this case the move 9 is in the top face of the bending-die a, while the ratchet-shaped rib a is in the lower face of the cutting-die. WVhen the cutting-die in descending cuts the blank, it forces it down through the fixed die B and against the bendingdies G, whereby the edges thereof are bent, as heretofore explained and as shown in Fig. 12.

In that bending-die G (on the left side of Figs. 11 and 12) which has the ratchet shaped recess there is a bar 9, extending from one end of said die to the other and set into a recess 9 Springs g in said recess beneath said bar act to force this bar upward, so that normally it stands in the position shown in Fig. 11. Thesprings holding it up are strong enough to resist the downward. movement of said bar until after the descending die on thatside of the machine has bent the edge of th'eblank at a downward over the inclinbd top edge of this bar. The furtherdownward movement of the die C pushes this bar down, so that its top ed e and one wall of its recess form the rate et-shaped groove referred to, and in so doing bends the extreme edge n of the blank upward in the verti tal position, as before described. The upward pro'ection of this bar 9, whose top face forms t e bottom of the ratchet-shaped groove when the bar is pressed down, causes the blank 'to be first bentalong the line n This of course withdraws the adjacent edge of the blank from the side of the fixed cutting-die and permits it to be bent upward when the bar is pushed down. If the edge of the blank were not so drawn inward by bending the blank, the edge of the blank would not infrequently be rolled in upon itself instead of being bent upward in a vertical plane. The blank having been cut and its edges having been bent as described, said blank is now ready to be bent around a form and the bent edges n n interlocked and subsequently pressed together to form the canbody. The form shown is a horn II, whose rear end is rigidly secured to the frame and the liners J J, which embrace it. It projects forward in the openings in the dies and bedplate, and its front end is normally supported y means of a pin is, attached to a slide K, which pin enters a central recess in the end of the horn. U )on this horn are movable liners J J about half as long as the horn. The horn itself, as shown, is nearly square in cross-section, being slightly round at the corners, and it is placed with said corners at the top, bottom, and sides thereof. In the upper and lower corners, respectively, are the longitudinal tapered grooves h h, which decrease in width gradually from the rear to the front end of said horn. Secured centrally in the bottom of these grooves and rejecting out therefrom are longitudinal y extended tongues 71 which are correspondingly tapered, being widest at their rear ends. The result is that on each side of each of these tongues (which, by the way, are only a little longer than the liners) is a groove of equal width from end to end but said grooves draw together from the rear to the front ends of the horn. Each liner consists of two side members 9' j, integral with each other and joined by rounded corners and lying at right angles to each other. On each free edge is an inwardly-extended tongue j, which tongues are inclined slightly from end to end of the liners, so that 'they fit into the grooves in the horn h h, before explained, on opposite sides of the tongues h, and the edges of the liners are in contact with the sides of said tongues.

These liners are placed upon the horn from the front free end thereof. When they are pushed toward the rear end. of the horn, with their tongues runnin r in said moves, they are expanded so that t ieir insid e dimensions beeome'larger than the external dimensions of the born, as shown in Figs. 13 and 14.

The tongues h project out from the horn such distances that when the liners are expanded the outer edge of one tongue it may e flush with and form a continuation of the surface of the liners and be a part of the form. At this time the other tongue It does not come out quite as far as the surface of said liners on the opposite side of the form. This seems leaves a. lon tudinal groove bl tween the liners oh-the ldwer side of the iornuinwhich the seam of the can-body is formed.

The liner-covered horn constitutes affirm, around which the blank is bent in forming; the can-body. In many ofthe claims it is referred to as e jjorm, end it is to be understood that this word is not intended .to indicate the specific form shown, but any form eclapted for 006 eretion with the other parts specified in sai claims.

The rear ends of the liners are loosely secured to a, slide Y upon the born. When the liners are in their normal positions at the rear end of the horn, this slide enge es erred- 'ustsble set-screw o carried by t e frerne. he liners are in the lest-described position upon the horn when the blank around the liner-covered horn. N after it has been out The blank 7 is bent around the liner-coveredhorn'h, the

Projecting into these slots are friction-rollers 1', which are mounted upon ins 1'', (shown in Fig i and sho n by dotte lines in Figs. e and 8,) which pins are immovable durinifihe downward movement of the slide E, on the slide E begins its downward movement, the bendingdies G G, carried by the lower slide member s, move away from the edges of the blank, thereby freeingit. The rollers P then press the blenlrdown u on'the form and bend it erounthe seine. T e arms M move 9. art and then together during the downwar movement of the slide, this movement being due to the guide-slots m and ins 'r, so that the rollers P Will'fOllOW the so see of seid'form, When the rollers P have carried the blank asfar around as preoticel, which is substantially to the position shown in Fig. 13, a. forming-die e, secured to the lower end of the 11 per member e of the slide E,engeges with t e top of the blank N, thereb pressi it with great force down upon t e form, t ereby finishin a part of the sen-body which the rollers P id not touch.

Darin these movements the liners have heen meeting edges 0* the two liners,

At this time it'wili he seen there is a groove between the lower the bottom of this groovebeing formed by the lower face of the 13m! ton h. 7 i; if ii Below the orrn there is s, slide S, the seam-forming die T and hainggsili' These hammers are slidable upon each other 111 a vertical groove in the die and fore normelly pushed up in the die b springs i, so that they project unequally a are the same.

It will be seen that the described construc tion permits the formation of a substantially squsre ceil firlywith the seem in one of the rounded corners thereof. Of course itis the shape of the liner-covered horn orform which determines the shape of the can-body, and therefore con-bodies of various shapes may be made by our loying forms heirin the rsuired' cisterns configuration. If it is desired that the body shrill be bonded, a circurn ferentisl rib i is formed upon the liners and tongues la and corresponding grooves p are formed in the bending-rolls P and in the face of the die T and hammers t t and die a. It is not necessary in the construction of the con-bodies that these bendin -rolls shall traverse the entire surface of t e blank. It isonly necessary that they shall en go with said blank near its front and rear e ds, for if the ends are drawn in upon the liners the intermediate ortions w ll follqw. thisreeson t rat the rollers niey'he constructed in the manner shownthst is to say, a shaft may be mounted inthe ends of the shaft between said rollers.

The slide S is given its upwsrd-end-downword movement at the roper time by an unusnsl sort of toggle ne of the toggle-onus ivoted to the slide 3, and one, it, is loose y hung on the drivin shaft. These toggle-erms erein the form 0 whiehrmesh, as shown. A spring it acts to rock link at, which causes the toggle to bend to the position shown in Fig. 6. Torock to form the ee.n-'-

presses it in. upon the linen-hoveredntdthe iiiu until the- B0 tivemovement of the hslrnrnersi While the them in the contrary direction to cause the upward movement of said slide, there is a disk V, secured to the shaft and carrying a pin n. This pin is parallel with the shaft and projects from both faces of the disk. ()n the inside of frame Ais fastened a disk a, with a cam-surface (1, aga' ist which the spring 12 presses the pin 1). n a certain part of the revolution of the shaft this cam pushes thepin through the disk sufficiently far to cause its other end u to engage with the edge of the toggle-link u, and thereby rock it in that direction which will cause the u )ward movement of the slide. When t 10 slide has moved up far e rough, the (:tlll-Slllfzbtt. a suddenly falls away and the spring t withdraws the pin o from engagement with srid toggle member.

It is of course desirable that there shall be an outwardly-turned flange on the lowerr nd of the can-body. This thereon while the blank is being bent around the horn, because that edge of tll( l)lat1il overhangs an annular shoulder j on the liners, and the forming-rollers P when they press the blank upon the liners will form the flange on the blank between this flange on the liners and the endeof the rollers.

All of the moving parts receive their motion from a single driving-shaft, wherefore their movements can be properly timed. The slide 1) is moved up and down by a lower W, which is pivoted to the frame of the maehine and has two forwardly-projecting forkarms 11. Pins we. secured to the slide, ezter slots in in said fork-arms. The rear end of this lever is connected by a conuecting-rod w with a vertical movable slide X, moving in suitable guideways in the frame. On the end of this slide is a pin a", on which is a friction-roller m. This roller enters a camgroove) in one face of a disk f, secured to the main driving-shaftF.

As above stated, the two liners are attached to a slide Y, embracing the horn. The attaclnnent is by means of bolts g, which pass loosely through slots in a flange on this slide and screw into the ends of the liners. The loose fit of these bolts in the holes permits the liners to have the movement toward and from the axis of the horn which. has been referred to. This slide Y is connected, by means of a linky, with another slide Y, which rests upon a horizontal member a of the ma.- chine-fraine. A part of this slide passes down through a slot a" in said horizontal member, and thereby the slide is guided. The art of the slide below the horizontal mem )er is connected by two rods g with the slide K, before referred to. These two rods are connected by a transverse rod y extending between them. A lever Z is pivoted to the frame of the machine, and its forked upper end engages with saidrod y. Its lower large n" is formed end is likewise forked and enga es with a pin .2, projecting laterally from a s eeve 2, which Slh es but does not turn upon a fixed rod 22. On another pin .2", projecting from this sleeve, is a frietionroller 2, which is engaged by a cam upon the driving-shaft, whereby this sleeve moves endwise. As soon as the canbody is formed the slide Y is moved toward the front end of the horn bv the described mechanism. It pushes the liners, on which is the finished can-body, along on the horn. Because of the convergence of the slots on which the linertongues are fitted the liners are drawn inward and are thereby contracted, so that the can-body may be removed. When the liners have reached the limit of their forward movement, the bottom end of the canbody will pass a springpaw1h let into the surface of the u per tongue h, which the horn carries, an the end of that pawl will spring up behind the bottom edge of the canbody, so that when the liners are moved backward, as the are immediatel after this, the can-body This can-body when the liners are back to their normal position drops down on the horn and removed therefrom by the next forward movement of the liners. On this slide Y are gri per-jaws L L for taking hold of the stocklieet to draw it into the ma chine. The lower gripper-jaw L is fixed; but the upper jaw is pivoted and has a long rearwardly-extended arm L. A spring I operates to close these jaws. ,The stock-sheet lies upon. a plate or table 0, which is pivoted on its front end on a transverse horizontal pivot. Its rear end is supported partly b resting on the front edge of the fixed die g and partly by resting upon a roller 16', mounted on the slide K. On the under side of this table is an inclined surface 0, with which this roller engages. When the slide moves forward to disengage the front end of the horn and to allow one of the can-bodies to be pushed therefrom, this movement is accompanied, as before explained, by the forward movement of the slide Y, which carries the gripperjaws. The slide K in its forward movement lifts the rear end of the table 0, on which the stock-sheet rests, so that the lower grip ier-jaw when it"raches the edge of said stoc -sheet may pass under it. At this time the upper gripper-jaw has been opened by the engagement of the upturned beveled rear end I of said gripper-]aw with a pawl I, hanging down in its path from a fixed part of the machine. This pawl is not capable of being swung forward bevond a vertical position, (shownin Fig. 5,) and so when the rear end of the gripper-jaw reaches and engages with it the jaw is opened. As the gripper-jaw moves still farther forward its end passes this pawl, and the spring closes the gripper-jaw upon the stocksheet. When the slides begin cos not accompany them.

. that the rollers 1? they carry do not toneh the .gri per-jaw is not f finished end headed bodies'presents no (Hill- P I scribed. i I am further of the opinion that sthis machine is the first which is capable of whilst sssgzss their rearward movement, the rear end the 7 movable gripper-j aw strikes this pawl and asit passes, so that the 0 ened; but when the sli es reach the end 0 their rearward movement this upturned end of the gripper-jaw engages with a fixed block 1, thereby causing the aw to open. The gri pers continue their rearward movement a ittle alter this time until the edge of the stocksheet is berel supported by a little forwardly-projecte tongue Z on the fixed grippenjaw L. The stock-sheet is now in position to have a blank out therefrom by the descending die C. It is desirable that the finished can-body shall be removed while the slide E is niovin upward; but this would not be possible i duringl the upward movement of the slide the ro lers were bearing upon the surface of said can-body. In order to draw these rollers away from the can-body and out of contact therewith before-the mechanism begins to remove said can-body, the friction-rollers r are mounted on eccentric-pins on the ends of the shafts R, which shafts are mounted in a cross-bar d", secured to slide D. Each of these shafts csrries a small inion r.' A- rocker r is assooiated with one of these pinions Hand is pivhted to the same cross-bar d and hes at one end a gear-segment which one gages with the corresponding inioni id anele anothergeor-segihent on the ct or end which: enga es with a fixed rack al".
